JOHN P. NIKONOW, OF NEW YORK, N. Y.

ELECTRICALLY-OPERATED IGNITION CONTROL.

Application filed September 14, 1926. Serial No. 135,475.

My invention relates to electrically oper ated ignition control for automobiles and has for its object to provide an electromagnetic device for retarding the spark for automobile engines. I further provide means to operate this electromagnetic device by a switch mounted. on the steering wheel within easy reach of the driver.

Usually the ignition device (the interrupter) is mounted so that it can be rotated through an arc of a circle in order to adjust the time of the spark, that is to retard or to advance it. F or this purpose usually a hand lever is provided on the steering post,

r connected with the interrupter (or ignition head) by means of a complicated system of roda links and universal oints.

VVit-h my construction all these mechani' cal connections become unnecessary. I provide a spring which keeps the ignition head fully advanced, and only when it is desired to retard the spark, it is necessary to press the button on the steering post.

My method gives only one step in retarding the spark, but it is sufiicientfor all practical purposes, considering that all modern ignition devices have automatic spark advance Within certain narrow limits.

I also provide an additional switch or contact button which can be operated together with the starter switch in order to retard the sparkwhen starting the motor.

My invention is more fully described in the accompanying specification and drawing in which Fig. 1 is a plan view of an ignition device with my electromagnetic device, also a steering wheel with a control switch and connecting circuit, and Fig. 2 is an elevation of an ignition devicewith my magnet.

hdly device consists oi a magnet 1 attached to a bracket 2 clamped by means of a bolt 3 to a tubular standard 4t of an ignition head or device 5 of an ordinary construction.-

This ignition head has an interrupter in its lower portion and distributor above (the inner construction of these parts is not shown). The distributor 6 has contact or terminal buttons 7 for leads to spark plugs (not shown).

The ignition head is rotatively mounted on a standard 8 with a flange 9 for attaching to an automobile engine (not shown). An operating shaft 10 is journaled inside of the standard 8 and has a gear 11 in mesh with a near 12 on a cam shaft 13. A lug 14 on the ignition head is pivotally connected with a link 15 which in turn is pivotally connected with an armature 16 of a magnet 1. A spring 17 tends to keep the ignition head turned in a direction opposite to the action of the spring. The rotation is selected so as to keep the ignition fullv advanced under action of the spring 17. The wires 18 and 19 connect the magnet 1 with .a battery 20 and a switch or cont-act button 21 mounted on a segment 22 on a steering wheel 23. The wires 18 and 19 form a loop around the steerinc" post so as to permit the turning of the wheel 23.

An additional switch 2-1 may be provided together with a starting switch (not shown) and adapted to be operated by the drivers foot in order to retard the spark when the engine is being started. In emergency, when the battery is very weak and it is necessary to crank by hand, in order to save the battery, the spark may be temporarily retarded by means of a hook 25 pivoted on the armature 16 and adapted to engage a stationary hook 26. This can be done by hand and the spark may be left retarded until the motor has been started, then the hooks 25 and 26 are manually disengaged.

The advantages of my invention are that it eliminates the complicated and troublesome mechanical connections from the steerinp; wheel to the ignition unit and adds to the convenience of operating the spark control when itis necessary or desired.

I claim as my invention:

In an electrically operated ignition control, the combination with an ignition unit of a magnetadapted to turn said unit to the position for retarding the spark, means to operate said magnet, means to support said magnet, means to keep said unit in a position for advancedspark when said magnet is not operated, and means to manually lock said unit in a retarded position.
